Matt Kettenhofen

Hello! My name is Matt Kettenhofen, more commonly referred to as Mr. K. I joined the Penryn family in 2017 and fell in love with the community and students at this school. There’s a very special feeling that you get at Penryn that can’t be described and I enjoy everyday that I get to work here.


I grew up locally in the Roseville area, I acquired my Bachelor’s Degree in Economics from Chico State, and then my Mathematics Credential from Sacramento State. I’ve been working in classrooms since 2014 and found that the strange, crazy creatures called middle schoolers are my people. In my free time I’m usually at the gym, out for a walk, or playing video games.


I have a passion for helping young people navigate through life and want to do everything in my power to help mold them into successful, intelligent, and caring adults. I look forward to many more years at Penryn.
